Abstract
The present invention pertains to metallurgical processes and equipment and, more particularly, to a metallurgical furnace capable of operating with a broad range of broad range of raw materials and fuels, including those with high levels of impurities. Accordingly, the metallurgical furnace of the present invention comprises (i) at least an upper tub, (ii) at least a lower tub, (iii) at least a fuel feeder positioned substantially between the at least an upper tub and the at least a lower tub, (iv) at least a row of tuyeres positioned on at least one of at least an upper tub and at least a lower tub, the at least a row of tuyeres fluidly communicating inside the furnace with the outside environment, and (v) at least a burner positioned on at least one of at least an upper tub and at least a lower tub. The use of at least a burner jointly with the at least a row of tuyeres generates a very intense release of heat by virtue of the exothermic reactions which occur by this combination.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
